Leucoplast vs. Chloroplast: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 9, 2024
Leucoplasts are colorless organelles storing starch, lipids, or proteins, while chloroplasts are green and conduct photosynthesis.
Key Differences
Leucoplasts are non-pigmented organelles found in plant cells, primarily involved in the storage of starch, oils, and proteins. Chloroplasts, on the other hand, are green due to the presence of chlorophyll and are crucial for photosynthesis, converting light energy into chemical energy.
In plants, leucoplasts play a key role in the synthesis and storage of various organic compounds. Chloroplasts are not just involved in photosynthesis but also in other processes like fatty acid synthesis and the immune response in plants.
Structurally, leucoplasts are generally smaller and vary in shape, adapting to their function in the cell. Chloroplasts are larger, with a complex structure including thylakoids and stroma, specialized for capturing light and performing photosynthesis.
Leucoplasts are found mostly in non-photosynthetic tissues of plants like roots, tubers, and seeds, while chloroplasts are predominantly located in the leaves and other green parts of the plant, where photosynthesis is most efficient.
Leucoplasts can differentiate into other types of plastids depending on the plant's needs, such as becoming chromoplasts during fruit ripening. Chloroplasts, however, maintain their role in photosynthesis throughout their lifecycle, being essential for the plant's energy production.

Leucoplast and Chloroplast Definitions
Leucoplast
Leucoplasts are non-pigmented organelles in plant cells for storage.
The leucoplasts in potato cells store starch.
Chloroplast
Chloroplasts convert light energy into chemical energy in plants.
In sunflowers, chloroplasts efficiently convert sunlight into energy for growth.
Leucoplast
Leucoplasts are involved in the synthesis of oils and proteins in plants.
Seeds often contain leucoplasts for the storage of oils and proteins.
Chloroplast
Chloroplasts are green organelles in plant cells responsible for photosynthesis.
Chloroplasts in the leaves capture sunlight for energy production.
Leucoplast
Leucoplasts are vital for the storage of essential nutrients in plants.
In corn seeds, leucoplasts store proteins vital for seedling development.
Chloroplast
Chloroplasts contain chlorophyll, giving plants their green color.
The green color of grass is due to the chlorophyll in chloroplasts.
Leucoplast
Leucoplasts are plastids found in roots and non-photosynthetic tissues.
In onion cells, leucoplasts are abundant due to their non-green nature.
Chloroplast
Chloroplasts are involved in processes beyond photosynthesis, like fatty acid synthesis.
Chloroplasts in olive trees contribute to the synthesis of fatty acids for oil.
Leucoplast
Leucoplasts can differentiate into other plastids based on the plant's needs.
The leucoplasts in tomato fruit may convert into chromoplasts as the fruit ripens.
Chloroplast
Chloroplasts have a complex structure with thylakoids and stroma.
The thylakoids in chloroplasts are where light-dependent reactions occur.
Leucoplast
A colorless plastid in the cytoplasm of plant cells around which starch collects.
Chloroplast
A plastid that contains chlorophyll and is found in the cells of green plants and algae.
Leucoplast
(biology) An organelle found in certain plant cells, a non-pigmented category of plastid with various biosynthetic functions.
Chloroplast
(cytology) An organelle, found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place, characterized by a high concentration of chlorophyll and two membranes.
Leucoplast
One of certain very minute whitish or colorless granules occurring in the protoplasm of plants and supposed to be the nuclei around which starch granules will form.
Chloroplast
A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms.
Chloroplast
Plastid containing chlorophyll and other pigments; in plants that carry out photosynthesis
